Winch spool

This spool is designed to work with 1" wide webbing. It has a hole for a 1/2" hex shaft used to turn the spool, and two 1/4" holes for bolts to hold everything together. Those holes are recessed, so they don't interfere with the webbing. One of the 1/4" holes has some extra clearance around the middle to allow the webbing to be looped around it and secured.

It also comes with a guide. The guide is designed to place the webbing on the spool, such that it doesn't come off and get tangled.
